Sichuan pepper is the dried husk of the prickly ash tree, prized in Chinese cuisine for its citrusy aroma and the distinctive numbing-tingling sensation (málà) it imparts to dishes.
History & Origins
Sichuan pepper appears in Chinese pharmacopoeias as early as the Han dynasty (206 BCE–220 CE), where it was described for both medicinal and culinary purposes, and by the Tang dynasty it was a celebrated regional product of Sichuan. Arab and later European traders carried it along the Silk Road, where it briefly rivaled black pepper in medieval European kitchens before falling from widespread Western use. In the United States, importation was banned from 1968 to 2005 to prevent the spread of citrus canker, after which authentic Sichuan peppercorns returned to global markets.
